What would happen if a spacecraft collided with an asteroid? The asteroid moon Dimorphos may have been reshaped following the impact from NASA’s Double Asteroid Redirection Test (DART), according to a paper published open access in Nature Astronomy: nature.com/articles/s4155…

Planetary scientist Ellen Stofan thought about leaving research after a funding bid was rejected. But new opportunities emerged go.nature.com/3Q1FjDI

Material delivered as a giant impact can dominate large portions of icy dwarf planets, according to impact sims. This may explain the shape and location of Pluto's Sputnik Planitia, without the need for a present-day subsurface ocean. Ballantyne et al.: nature.com/articles/s4155…

The Moon is not a grave, write Frank Tavares and colleagues. NASA must uphold its promise to consult with Indigenous communities regarding the use of space.

The Cluster spacecraft has found direct evidence of the theorised Alfvénic transition from weak to strong magnetohydrodynamic turbulence, enhanced by nonlinear interactions, which can be present in many kinds of astrophysical plasma. Zhao et al.: nature.com/articles/s4155…

Including stellar surface magnetism in models of limb darkening resolves an outstanding discrepancy with observations. This enables improved characterization of transiting exoplanets and a method for measuring stellar magnetization. Kostogryz et al.: nature.com/articles/s4155…

On its way to Mercury, BepiColombo flew by Venus for the second time and could measure the flux of heavy planetary ions like O+ and C+ in the flank of Venus's induced magnetosphere, escaping from the atmosphere. lina hadid et al.: nature.com/articles/s4155…

JWST obs. of GRB 221009A reveal the associated supernova, confirming the GRB resulted from the collapse of a rapidly rotating massive star. The lack of r-process emission suggests these events are not key sources of the heaviest elements. Blanchard et al.: nature.com/articles/s4155…

A research team led by Kristina Kislyakova from Universität Wien has for the first time directly detected #stellarwinds from three Sun-like stars by recording the X-ray emission from their #astrospheres , and placed constraints on the mass loss rate of the stars via their stellar winds.

The solar corona is very hot in general, but it is especially hot, up to 10 million Kelvin, over the cores of active regions. A model from Lu et al. shows that continuous flux emergence from magnetic reconnection steadily heats this plasma. nature.com/articles/s4155…

The finding of ferroan anorthosite in the Vestan meteorite NWA 15118 provides observational evidence of the formation of a magma ocean during Vesta's early history, which then crystallised in multiple stages. Li et al.: nature.com/articles/s4155…

Out now in Nature Astronomy: the first definitive detection of linearly polarised radio waves being converted into circular waves around one of the Universe’s strongest magnets!

A radio magnetar has been observed to precess shortly after an X-ray outburst. The precession decayed over the next few months and likely rules out freely precessing magnetars as the source of the fast radio bursts. Desvignes et al.: nature.com/articles/s4155…

Using the Murriyang and Lovell telescopes, astronomers discovered the radio pulses from a rare, radio-loud magnetar displayed a mysterious conversion in their polarization state that are linked to changes in its magnetic field geometry. Marcus Lower et al.: nature.com/articles/s4155…
